ROAD-SCRAPER.

SPECIFICATION forming part of Letters Patent No. 301,051, dated June2li, 1884.

Application filed February 14, 1884. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM ELLIs, Jr., a citizen of the United Statesof America, residingat North Lawrence, inthe county of Douglas and Stateof Kansas, have invented certain new and useful Improvements in Road-Scrapers; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters y or figures ofreference marked thereon, which form a part of this specification.

My invention relates to that class of roadscrapers which aredouble-ended and constructed to revolve for the purpose of dumping itscontents; and it consists in the arrangement and construction of thevarious parts thereof, so that the effective operation of 'the device isreadily secured.

In the accompanying drawings, Figure l is -a perspective view of myimproved road- Scraper. Fig. 2 is a perspective view of theoperating-frame, the end of the lower lever being'slotted, as indicatedby dotted lines, Figs. 1 and 2, to permit the pivot-bolt to play thereinwhen the said ends are moved rear-V scraper, so as to revolve therewith.Each of if these rollers b is cut away at its periphery to formshoulders c d, each being half the width of the-periphery and reversed,as shown in Fig. 4.

Y A metallic ease, B, is secured to the forward end of each of thehandles C, and is provided with a perforated extension, e, at its front,adapted to engage one of the journals a of the scraper. Through eachcase B play two bolts,

ff', one of which bolts, f, is connected at its rear endto theperforated `end of a lever, g', centrally pivoted on the cross-bar D,connecting the handles. The levers g are pivotally connected together attheir inner ends. A curved hand-lever, h, is pivoted to the end of eachof the handles U, and is connected at its forward end to the outer endof the adjacent lever g by a link, t'. A tension-spring, E, is securedon the bottom of the cross-bar D, as shown in Fig. 3, and has itsextremities extended to engage the outer ends of the levers g, as shownin Fig. 2. This'tension-spring tends to maintain the outer ends of thelevers g in the position illustrated. A small handlever, F, is pivotedon the cross-bar D at the rear of the central connection of the leversg, and said hand-lever carries at one end a roller, j, journaledlooselyon its end, and adapted, when said hand-lever is moved in a positionparallel with the handles G, to bear against the inner connected ends ofthe levers g and force them forward, thus throwing the outer endsrearward. Two plates, G, of spring metal,

are secured at their upper ends, one to the inner side of each of thehandles C, so as to depend therefrom, the ends le of said plates beingbent up, as shown in Fig. 2.

Thedraft-bail II is bent in toward thesides of the scraper A, so as toform extensions lof said draft-bail. vBrackets I, provided with .bladesan, are adapted to be secured to the sides of the scraper A, as shown inFig. 1. The bolts f f arranged side by side, are adapted to engage theshoulders c cl of the disk, which shoulders being reversed will causethe bolt f to be above the shoulder c, while the bolt f is below theshoulder d. The bolt f is Spring-seated in the case B, so as to yield,but may be otherwise connected to be retracted within said case whennecessary.

By depressing either of the handles 7L the outer ends of the levers gare drawn backward against the spring-tension, thus withdrawing thebolts fand permitting the weight of the load in the scraperto dump andrevolve the scraper, the position of the bolt f with regard to theshoulder d preventing any reverse movement of the scraper. Vhen theScraper revolves forward, the disk b turns therewith and forces the boltf back into the case until IOC) the terminus of said shoulder isreached, at of the supporting-frame, and provided with which point thebolt is forced beneath said shoulder to occupy the position firstdescribed.

By making the case B and its extensions e in one piece the parts may bereadily cast and great durability secured, and thc entranceof dirt toprevent the working of the bolt pre- 'contact with said ends, but opposeany downward movement of said scraper.

Should the frame composed of the handles C and their connections bethrown forward accidentally or otherwise, the said handles will come incontact with the extensions Z of the draft-bail H.

The cutterbrackets I insure the regular trimming of the sides of thespace in which the scraper travels.

I claim- 1. vrIhe combination, in a road-scraper, of a scraper properpivoted in a suitable frame by journals, and provided with a disk havingreverse shoulders located in parallel peripheral planes, as described,and bolts arranged and operating to respectively prevent the forward andrearwardrotation of said disk, substantially as set forth.

2. The combination, in a road-scraper, of a scraper proper pivoted in asuitable frame by journals, and provided with a disk having reverseshoulders, and two bolts arranged on the frame supporting the scraperproper, one operated by hand-lever connections secured on the frame andthe other automatically yielding, substantially as described.

3.- 'Ihe combination, in a road-scraper, of a scraper proper havingjournals located at its l sides, a notched disk secured to said scraper,

a case secured on one side at the forward part an extension perforatedto receive one of the journals, a bolt playing through said case, anddevices for operating the same, substantially as described.

4. rIhe combination, in a road-scraper pivdisk, and handles pivoted ateach side of the upper end of the frame and connected with said boltdevices, substantially as set forth.

5. The combination, in a road-scraper, of a scraper properpivoted in aframe, bolt devices for locking it in its pivoted position, mechanismfor disengaging said bolt devices, and means for locking 4said devicesintheir disengaged position, substantially as set forth.

6. The combination,` in a road-scraper pivoted in a suitable frame byjournals, and provided with. cutter-brackets bolted to the sides of thesame, of a disk having reverse shoulders located ifparallel peripheralplanes, as described, and bolts arranged to respectively prevent theforward and rearward rotation of said disk, substantially as set forth.

' 7. The combination, in a road-scraper, of a suitable frame providedwith depending plates G, bent and arranged for the purpose set forth, ascraper proper pivoted in said frame, and provided with a disk havingreverse shoulders located inparallel peripheral planes, as l
